This is the largest layer of the interior of the earth
The mantle
The surface of the earth is divided into _____ number of plates
15
The name of the Supercontinent, where continental drift started to happen.
Pangea
this machine is how scientists can detect Earth's Movements in the lithosphere
seismograph
The difference in arrival times for the P and S wave was 4 minutes and 30 seconds. How far away is the Earthquake?
3200 km
tremendous heat and pressure cause the liquid mantle to rise, spread, and sink. These kinds of currents are responsible for plate tectonic movement
Convection Currents
this formation occurs at convergent plate boundaries, where molten rock is pressurized and erupts and causes severe destruction.
volcanoes
When two plates begin to move away from each other, this plate boundary is formed
divergent plate boundary
S-waves
The s-waves of an earthquake arrived 00:07:20 after the p-waves. How far away was the earthquakes epicenter?
5600 km
This is the layer of the mantle that is directly underneath the lithosphere
astenosphere
draw a cat on top of the earth. best drawing receives points.
2) Nazca and South American
These waves travel fastest, and are recorded first.
P waves
3) 4,000 KM away
The two metal materials that make up the majority of earth's core
Iron and Nickel
When oceanic crust is forced down from continental crust at convergent plate boundaries, this formation occurs.
subduction zone
The crack in the earth's crust where stress is suddenly released causing an earthquake.
Faults
This is the scale used to measure the actual amount of seismic activity or magnitude of an Earthquake.
Richter Scale
3) 4:36 pm
This is the outermost layer of the earth, where humans are located.
Lithosphere/crust
this kind of crust is thinner, denser, and made of basalt
oceanic crust
The San Andreas Fault is located along this kind of plate boundary
Transform plate Boundary
this is the term used when seismic waves travel through the earth, caused by movement of the Earth's plates.
earthquake
Which station was closest to the earthquake's epicenter, and WHY?
Station C
